If so, I don't think its possible. I tried it also with virtualbox and was unable. I did some research and tweaks but couldn't find an answer except that "it wont work" - probably because Xen hypervisor depends on full hysical CPU access. The Xen hypervisor is pretty stable, I don't see why you couldn't get it running on a Linux workstation. Also note that with some computers you need to turn on Virtualization Technology in the BIOS.

And there can only be one kernel at a time. I know that with VMware there's a thing like VMware ESX server in VMware workstation (combination could be slightly different ;-)) possible. I don't know that much about the XEN internas to say if it's possible to modify XEN, so that something similar is possible. I once tried building a XEN dom0 kernel under VMware workstation 6.0 but the building process itself failed with some errors on APIC. -- Mr. Olli Am Montag, den 09.02.2009, 20:39 +0100 schrieb Julian Stecklina: > Hello, > > I am trying to build a kvm (or VirtualBox) virtual machine to painlessly > experiment with Xen on my 32-bit Linux laptop (Core Duo L2400 with > hardware virtualization foo) or my 64-bit Linux desktop box (Phenom > 8450).

You're likely to run in to problems on less mature platforms that rely on hardware virtualization. However, there is no fundamental reason that paravirtualized guests should not work there.

That happens every couple of minutes. I set up a cron job setting the correct time via ntpdate every minute but that is a problem when the time jump happens during ntpdate is just running - it hangs then. There is no cpu and no io load on the machine which might correlate with the time jumps. Any idea what might cause the problem? XEN is 3.2.0 with Linux Dom0.
